Playground

The Soqucoin Builders Playground is a browser-based development environment for quantum-safe transactions.

Stagenet only

Throwaway keys, no real value. A developer preview.

What it does

  1. Generates an ML-DSA-44 keypair in your browser (via @noble/post-quantum)
  2. Derives a Bech32m address (ssq1p...)
  3. Funds from the stagenet faucet
  4. Builds, signs, and broadcasts a real transaction — all client-side

The private key never leaves your browser. The gateway at gateway.soqu.org provides UTXO data and broadcast; your browser does the signing.

Wallet persistence

The keypair is stored in localStorage under key soq_playground_wallet_v1. It survives page reloads but is lost if you clear site data. Click Regenerate to create a fresh keypair.
